If there is even a remote chance you'll buy or lease a new or CPO BMW within the coming year, get hopping and renew now! A lapse of even one day renders you ineligible for the Member Rewards program:

2011 Program Terms and Conditions

ÃƒÆ’Ã†â€™Ãƒâ€šÃ‚Â¢ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡Ãƒâ€šÃ‚Â¬ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â¢ A membership of one year or more immediately preceding the delivery date of the vehicle is required to take advantage of this program. A member in good standing cannot have any lapse in membership during that 12-month period.

(Sorry for the OT post, I just would hate to see you miss out on free money.)
